Mecha Bots The concept behind this game is the construction of warrior robots that fight each other. But the mechanics of the construction are different. Hexmap based.

Metamorph (80% complete) A game of shapechanging mages in a fantasy setting

Morituri te Salutant (10% done) Possibly this could be viewed as “Battle Bots 2”. There's elements of Wings of fury in it now. I like the concept of different decks for different people. Update - there's already a gladiator game with this name using this mechanic (great minds think alike!) - you can find it here- http://boardgamegeek.com/boardgame/36709/morituri-te-salutant
On a side note, apparently the phrase is apocryphal and was a-typical.

Rollerball v4 A single route/multiple route game. I imagine a square board with multiple concentric rings.

Storm the Castle Players are groups of peasants bent on bringing down the mad scientist in his evil mansion. Inspired by the World Works paper model of Shellendrak Manor.

Thief (30%) Inspired by the various Thief games from Looking Glass Studios that have been part of my favourite computer games of all time. I really should have started designing a boardgame about them well before now.

Trove Mentioned in passing as an amusing pun of Trovial Pursuit by a work colleague. However - I think it has game potential.

Cyber Wedding v2 What happens when you gather a bunch of geeks and their families, dress them up according to different time periods and perform a wedding?
Well, the obvious of course - an invasion by Cybermen who think there is time travel technology present. Prepare to be upgraded.

Tower Defense An attempt at turning a computer game genre into a board game
